Corsair Vengeance LPX 32GB (2x16GB) DDR4-2666MHz CL16 Desktop Memory Kit — Black
The Corsair Vengeance LPX CMK32GX4M2A2666C16 is a 32GB (2 x 16GB) DDR4-2666MHz desktop memory kit for anyone upgrading RAM on a standard desktop PC — sold as a matched pair, not two separate sticks.
Compatibility
This kit uses standard 288-pin DDR4 DIMM modules, so it fits any desktop motherboard with two free DDR4 slots. It runs natively at DDR4-2666MHz with XMP 2.0 support for automatic speed and timing setup on boards that support XMP profiles. Our listing specifies compatibility with Intel X99 and 100-Series motherboards — if you're on a different chipset (older, newer, or AMD), check your motherboard's supported memory speed in its manual before ordering. Running below 2666MHz won't damage anything, it just won't hit the full rated speed.
Specs
- Capacity: 32GB total (2 x 16GB modules)
- Speed: DDR4-2666MHz (PC4-21300)
- Timing: CL16 (16-18-18-35) at 1.2V
- Form factor: 288-pin unbuffered DIMM, non-ECC — standard desktop memory, not for ECC/server boards
- Heat spreader: anodized aluminum, low-profile design for CPU cooler clearance
- Colour: Black
What's Included
- 2 x 16GB DDR4 DIMM modules (one matched kit, total 32GB)
- No mounting tools, software, or lighting accessories included
Why It's the Right Pick
Each module is individually screened before pairing, and the kit uses an eight-layer PCB designed for stable performance at rated speed. If you're replacing failing RAM or adding capacity for multitasking, content work, or gaming, this kit gives you a tested, matched pair rather than two mismatched sticks bought separately — which matters for stability more than most buyers realise.
Is this one stick or a matched kit?
It's a matched kit of two 16GB modules (32GB total), tested together as a pair.
Will this work with my AMD Ryzen motherboard, or is it Intel-only?
Our listing confirms Intel X99 and 100-Series compatibility. DDR4-2666 is a standard speed most AMD AM4 boards also support — check your board's memory list to confirm.
Do I need to enable XMP for it to run at 2666MHz?
Yes. Most boards default to a lower speed until you enable the XMP profile in BIOS.
What does CL16 (CAS latency) mean for performance?
CL16 is a mainstream, balanced latency rating — solid for everyday desktop use and gaming.
Is this low-profile — will it fit under a tall CPU cooler?
Yes, it uses a low-profile heat spreader that clears most tower air coolers.
Can I mix this kit with RAM I already have installed?
Not recommended. Mixed kits can force everything down to the slowest module's speed or cause instability.
Is this ECC memory, for use in a workstation or server board?
No — it's non-ECC, unbuffered memory for standard desktop boards only.
Does this kit include RGB lighting?
No. This is the standard Vengeance LPX line — no RGB, aluminum heat spreader only.
